MAX7219 8-Digit 7 Segment Display Module

This 8 digit seven segment display module is based upon the Maxim MAX7219 LED display driver. The module uses two standard 4 digit seven segment displays to display a total of 8 digits in RED with decimal point. A convenient input and output header allows additional modules to be daisy-chained and controlled with just 3 digital IO pins.

The Maxim MAX7219 driver allows for each segment of up to 8 digits (with decimal point) to be controlled individually from a serial interface. An 8×8 static ram area stores each digit and multiplexing the display is handled automatically.
